Networking relented example fails to run (unix & ukvm) about mirage-skeleton

[ciarancourtney]

Using mirage configure -t unix --net socket as per the Hello World tutorial on mirage.io resolves the issue for the unix case

hey, in your error message your Linux complains about Operation not permitted while setting up the tap interface. you may want to execute ukvm-bin as superuser (e.g. with sudo ./ukvm-bin --net=tapX <kernel>.

@hannesm thanks, but passing --net socket as per above resolves the permission issue, so that works fine without sudo. For the ukvm case I see that --net is an arg that was missing from the docs, it boots and says its on 10.0.0.2 but I can't ping/curl that from localhost

@ciarancourtney ic. on your host system, you'll need an IP address in the same subnet... some ifconfig tap0 10.0.0.1 netmask 255.255.255.0 should do the trick (and then ping 10.0.0.2 should work).

@ciarancourtney I'm closing this issue, but please do reopen it and let us know more if you're still having difficulty getting the networking examples running.
